‘AVERAGE Joe’ has turned out to be such a hit for NBC, the network is readying a sequel for January.

“We may have outdone ourselves with the casting, it’s much more extreme,” executive producer Stuart Krasnow told The Post yesterday of the eclectic and downright dorky-looking bunch of guys cast for season two of the reality/dating show.

“I think they might make the first group look like Adonises,” he said. The new season, “Average Joe: Hawaii” is expected to debut on January 5.

On “Average Joe” a group of somewhat normal guys – most of whom classify themselves as nerds and geeks – vie against each other to win the hand of a beautiful girl.

On the current installment, Melana Scantlin, a former beauty queen and NFL cheerleader has narrowed the field down to four. The season finale is on Dec. 8.

Two of the finalists are hunky underwear models that the producers threw into the game in a surprise last minute twist.

But neither Melana nor the new girl for season two were told that most of their suitors would look more like TV nerd Steve Urkel than Brad Pitt.

“She’s an artist, she’s a former beauty queen from a known pageant and she’s a brunette,” Krasnow said of the new girl. “She’s extremely intelligent and very compassionate.”

But like Melana, the new girl was upset after she was first presented with her “visually interesting” assortment of suitors.

“Her reaction was disbelief and anger,” said Krasnow.

Melana was rumored to have stormed off into the desert around the Palm Springs mansion where “Average Joe 1” was filmed, before settling down and playing the game.

At the time Krasnow said he would “never want to repeat that first night.” But the second time – filmed last summer on Big Island, Hawaii – “was much worse. We had a very long night taping, let’s just say we saw the Sun come up,” he said.
